    So I was on a ride the other day and after about 100 miles we pulled off and sat at the gas station for a minute talking, When I went to leave I flooded My Xj650, the fellow I was riding with whom I had never met before told me to turn my choke all the way off, open the throttle all the way and start it. Sure enough it started right up. Can anyone explain to me how that works.

    It sounds like you have a faulty petcock. The stock ones are vacuum operated and should stop the gas when the engine is not running. You may need to rebuild yours to avoid that.

    The other part to the issue would be a stuck carb needle that stayed opened flooding your carbs.

    Closing the choke prevents extra fuel from entering the intake (you shouldn't need the choke on a warm engine). Opening the throttle lets in more air. Combined, those two actions get the fuel/air mix closer to the ideal ratio so the engine can fire, once the extra fuel in the cylinders gets pumped out.

    The next time you stop for gas don't use the choke to restart the engine. It's already warm and dosen't need the extra fuel.

    Yea that makes good sense, rookie move on my part. The petcock and carbs have been rebuilt by me last summer and I've had it on the record regular ever since so I wouldn't think it would be those. Thanks K-moe.
